DryBase Liquid Applied DPM

DryBase Liquid-Applied Damp Proof Membrane (previously known as DryBase Vapour Membrane) is a single-pack barrier coating that is supplied ready to use straight from the tub or pail. The product is supplied in black or white with a consistency similar to that of thick emulsion paint.

Once applied, the product cures to form a membrane that is flexible and elastic. DryBase Liquid-Applied DPM is water-based and can be applied to damp substrates by brush, roller, or spray. The applied product is typically touch-dry in one hour.

Once cured Drybase Liquid-Applied DPM provides a barrier to damp and ground gases (including radon, carbon dioxide, and methane).

Each 5 litre pack will cover up to 4.5m2 depending on the substrate surface texture.

Typical applications for DryBase Liquid-Applied DPM include:

Gas barrier (radon, methane, carbon dioxide)

DPM for floors

Damp-proof barrier

Flood resilience and mitigation

Isolating embedded timbers (e.g. to protect against dry rot)

Damp-proofing of reglet joint

Bunds and silage tanks.
